This object remaps the model coordinates using a Lambert conformal conic projection with user-defined parameters. The x-coordinate then becomes the value of the (east positive) longitude in decimal degrees, the y-coordinate becomes the (north positive) latitude in decimal degrees and the z-coordinate becomes the altitude in metres.

The syntax in parameter files is

GfsMapProjection {
  lon = 174
  lat = -41
  angle = 40
}

with

lon
the longitude of the center of the reference GfsBox.
lat
the latitude of the center of the reference GfsBox.
angle
an optional rotation angle in the lon-lat plane (default is zero).
